UNITED srATes PATENT EMBROIDERY FRAME- t Application .filed rApr-i1 21, 1,923. `Serial No. 633,719.

rilhis invention contemplates `the provision of an attachment for embroidering Ama- `ehines, the attachment being inthe nature of a floating frame to which .the kmaterial ,is Secured,the frame being designed to support diderent pieces of fabrics, such as handkerchiefs -or other novelties for veac-h needle, kand yhold the lfabrics so that .any particular lpart lof the same canbe embroidered.

The chief object of Ythe .invention resides in providing a Vfloating frame attachment for machines of theabove mentioned .character, characterized bythe ease with which the fabric vcan be 'attached .to .or ,removed from .the lframe, as the V,occasion may require.

The nature and advantages of the linvention will be better understood when the following .detailed description 'isv read in `connection with ,the .accompanying drawings, .the invention residing i, in :the construction, combination and arrangement .of parts .as claimed. l

Figure 6 is a detail .View Iof a pair Of clamping `rods showing the ,connection ibetween the same.

The yframe above-.referred to is adapted lto be clamped in numbers to embroidering machines in vertical positions and yeach frame is made up .of a plurality of vertically kdisposedloars 1() which arearranged .in vspaced parallelrelation and of channel like formation in cross section. rrlhese bars are associa-ted y,with end members as shown,each member b eing of substantially l-L-.Shaped formation in cross sectionand .including spaced parallel portions 11 and .12 respectively. These portions are'notched vas at v13 to .ac- .commodatethe adjacentfendsof thezbar's 1.0 vas well Las the clamping rods to .be .herein. after described. The innermost portion 12 of each end member is kutilized to vhold lthe end members associated lwith the bars 10, the latter terminating at both ends to provide attaching portions 14 which are arranged in contacting engagementwith the said .portions .12 of the end members, and secured thereto b y suitable fastening elements 15. rlhesgaced portions 11 and 12 `of ,eachV .end 'member have arranged' therebetween spaced elements 16, disposed at either side ofthe notches 13andpivotally lassociated Vbetween these spacing elements are hooks .17 which are arranged to :engage the clamping rods 18 to hold .the latterv vin clamping position. As will .be noted Afrom the drawings, there are vtwo of Athese rodsv associated with .each vert-ical bar 1Q, and each rod is constructed of resilient 4material normally curved. The adjacent ends of each pair of rods 18 are formed'wit-h eyes 1 9, `so .that these rods vare pivotally mounted lon pins 20 supported by ar .U-shapcd member211designed .to iit'within the channel bar 10 at a point vbetween the ends thereof. y,Each `:rod 18 .is partly covered'with a sleeve 22 .of relatively soft material, suoli as rubber, Vcloth or the like, so that-.these rods will notin'jurethe yfabric which is clampedto the frame by Lmeansof said rods. The rods are .of a .length to extend slightly beyond .the

,endfmembers ofthe frame being received by the notches l13 yand held in extended or ,straightened positions'b;7 the adjacent hook .like elements 17. l-Conseqiently, when the .rods are thus arranged, they are placed .unl der .tension toeifectively Vgrip .and .hold the .fabric 22 secured tothe adjacent bars 10 as shown in Figurel of the dra-wings, thehook like .elements 17 .as above stated hold ,the :rods inclamping position within the channel .like bars 1D. The hooks 17 are balanced'ligravity hooks, land automatically engageand 4disengage the springrods.

'The frame is divided into upper V,and .lower sections by a transverse .member 23 .which is also of channel formation in cross section and provided with notches in .its sides to receive thebars 10, so that the upper or open edges. of `these bars lie flush -withthe -open sidebf the member This vmember ,23 as above set forth is of substantially 4.channel 1formation .in cross section,y and each .parallel Vside terminates to provide .a Ysubstanltially L-shaped flange 24.. As a matter of fact, the ltransverse .member j is ,made .up of ra plurality of spaced U-shaped portions 23" connected by the L-shaped flanges 24. The

bottom of each U-shaped portion is cut-away kalong the opposite sid-es of the longitudinal center, and the material thus cutaway in each instance is bent to provide parallel ears 26 between which the bars A10 are clamped, the pin 2O upon which the clamping rods are mounted, being utilized as means for clamping the ears to the bars l() as shown in Figure 5 of the drawings.

Arranged within the transverse member just described is a plurality of pivoted spring pressed clamping elements 28, each of which is of L-shaped formation. These clamps are arranged in pairs between the vertical bars l0, and are pivoted between spaced apertured lugs 29 which are struck from the bottom of the U-shaped portions 23 of the transverse member as illustrated in Figure 5. It will be further noted that the clamping members 28 of each bar are reversely disposed, so that one branch of each clamping member cooperates with the adjacent L-shaped flange 2e of the transverse member for the purpose of clamping a portion of the material or fabric to this niember. This particular branch of each clamp is indicated at 28', and while the clamping portion is constructed of metal or other suitable material, it is covered by rubber or other relatively soft material, so that the fabric will not be injured by being clamped between the L-shaped flange and said clamping member. Positioned between each pair 'of clamping members is a plate 30, which plates also lie between the adjacent U- shaped portions of the transverse member. The plates 30 span the spaces between the U-shaped members 23, and form needle guards to prevent the needles of the enibroidering machines from getting caught in that portion of the fabric held by the branches 28 of the clamping members 28, as it will be obvious that a portion of the fabric will extend inwardly beyond the L-shapedy flange 24 and be disposed upon the outer surface of the plates 30. In other words, these plates 3() protect the fabric from the needles of the embroidering machines when the frames are raised or lowered in the machines for moving the needles of the machines from one section of the frame to the other when it is desired to embroid-er the material in the opposite sect-ions as will be' readily apparent. rtherefore, it will be seen that the space between the Ushaped meinbers 23 and below the plates 30 will provide needle passages 30 and yet the portions of the fabric extending into the U-shaped members will be amply protected. It is by means of these passages that the needle passes from one fabric holder to the other thereby malring the double fabric holder possible.. It is quite obvious from the construction illustrated and described that handkerchiefs, novelties or other fabric can be easily and on said machine. In practice, while one set of frames is arranged on the embroidery machine, with material therein being embroidered, another set of frames are being vfilled with material to replace the set in the machine, when the work on the material in the last mentioned set is finished. Of course, a single frame as shown can be clamped to an embroidery machine.

From the above, it will be seen that the frames are to be vertically disposed with respect to the embroidery machines, and the needles of the machines operate on the material in one section, preferably the upper section' of the frame, and then the frameis moved 'upwardly so that the needles can operate on the fabric in the lower portion of the frame. The fabric is shown in the lower portion of the frame in Figure 1 of the drawings. lIn moving'the frame, vertically on the embroidery machines, it'will be i obvious that the needles will remain stationary, and the needle passages 30 which are disposed between the members 23 allowthe vertical movement ofthe frame withoutfear of the needles catching in the'fabric duringV i the process of moving the frame.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I

desire to have it understood that I' do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the l scope of what is claimed.

Having thusl described the invention, I claim: z

l. A fabric supporting frame of the character describedY including a plurality ,of spaced vertical bars, each'bar beingof channel formation, a transverse member connecting all of said bars centrally thereof, normally curved resilient rods arranged in pairs in each bar, and having their adjacent endspivotally mounted on the bar, balanced gravity hooks for holding said rods withiny said bars andparallel therewith for clamping a portion of the fabric to the bars, and substantially L-shaped clamping members carried by the transverse member for clamping the adjacent portions of said fabric thereto. v v

2. A fabric supporting frame ofthe chariso acter described including a plurality of spaced vertical bars of channel formation, end members connecting said bars7 a transverse member arranged centrally of the frame and associated With all of said bars, said transverse member being of channel formation in cross section, and made up of a plurality of U-shaped members, substantially L-shaped in cross section iianges connecting the U-shaped members and cooperating clamping means arranged in said bars and said U-Shaped members for clamping the adjacent portions of the fabrics to the frame for the purpose specified.

3. A fabric supporting frameV of the character described including spaced vertical bars, said bars being'of channel like formation in cross section, a transverse channel like member connecting said bars centrally,
